She reiterated that Barzee, a mother of six, stood by as her husband, street pastor Brian David Mitchell, raped the then-teenage victim daily.

Mitchell, who took Smart at knife point, is serving life behind bars.

"I do believe she’s a threat," Smart said. Later, she added, "For me, I know the depth of her depravity."

Scott Williams, Barzee's attorney, told NBC affiliate KSL that his client would be released under terms that include supervision. NBC News reached out for his reaction to Smart's remarks but did not get an immediate response.

Barzee was sentenced in 2010 to 15 years in federal prison for her role in Smart's 2002 abduction from her Salt Lake City bedroom. In 2016, she was released but faced one to 15 years in state prison for a separate attempted abduction of Smart's cousin.

The board this week stated that after a recent legal review of Barzee's time behind bars, it has discovered that six of the years she spent in federal prison should count toward the state sentence, thus making her eligible for release.

Late Thursday the board's director of administrative services, Greg Johnson, said by email that it has no choice.

"The Board has heard concerns and requests to reconsider releasing Wanda Barzee. This is not an early release or a discretionary release," he said. "Ms. Barzee cannot be legally held in the Utah State prison beyond the length of her sentence."

Smart said that, as a Christian, she forgave Barzee years ago but it doesn't mean she would ever "let her her back into my life."

"I would urge the powers that be and anyone that works under them to strongly reconsider this situation," Smart said. "Wanda Barzee saw me as her slave ... She did appalling things while I was in captivity.
